If you're open to cosplay that's not Anime, there's some good black characters in the Star Wars universe, both movies and video games. And a decent percentage of those are Jedi
Star Wars has a lot of room for original characters too- Jedi, Sith, Mandalorians, etc..There's a lot of character concepts you can use to form your own creations. Don't let your skin color deter you from doing something you love!
